The graph of a compound inequality with an or represents the union of the graphs of the inequalities. This tutorial will take you through the process of splitting the compound inequality into two inequalities.
Can you give details about what exactly is the graph inequalities on a number line calculator homework that you have to solve.

Now its time to learn how to solve quadratic inequalities.
Plus i have this great software algebrator that i downloaded from the internet which is soooo good at solving algebra homework.
The solution of a compound inequality that consists of two inequalities joined with the word and is the intersection of the solutions of each inequality.

A number is a solution to the compound inequality if the number is a solution to both inequalities.
It can either be written as x 1 and x 2 or as 1 x 2.
If it is unclear whether the inequality is a union of sets or an intersection of sets then test each region to see if it satisfies the compound inequality.
Find the number on the other side of the inequality sign from the variable like the 4 in x 4.
